2,6-dichlorophenolindophenol ( DCPIP ) is a blue chemical compound used as a redox dye. In Oxidized form DCPIP is blue;whereas in reduced form DCPIP is colorless.The rate of photosynthesis can be measured by the rate at which this dye changes color (is reduced) when exposed to light in a photosynthetic system. This reaction is reversible, as colorless DCPIP can be reoxidized to blue. Blue redox indicator dye used for the determination of Vitamin C (ascorbic acid), which when Vitamin C is present reduces to a colorless hydroxy compound. May be used as an electron acceptor and to stain glutathione reductase electrophoresis gels. Also known as Tillman's reagent.

Applications:

2,6-dichlorophenolindophenol (DCPIP) is used as a substitute for NADP+. The dye changes color when it is reduced, due to its chemical structure. The rate of photosynthesis light-dependent reaction can be measured with this property of DCPIP, because one of the stages of the light reaction is an electron transport chain that normally ends with the reduction of NADP+. When DCPIP is present, it also gets reduced by the light reaction. The amount of DCPIP reduced can be found by measuring the solution's light transmittance with a spectrophotometer. 2,6-dichlorophenolindophenol sodium salt is a redox dye commonly used as a monitor of the light reactions in photosynthesis because it is an electron acceptor that is blue when oxidized and colorless when reduced. It is part of the Hill reagents family. DCPIP can also be used as an indicator for Vitamin C. If vitamin C, which is a good reducing agent, is present, the blue dye, which turns pink in acid conditions, is reduced to a colorless compound by ascorbic acid. 2,6-Dichloroindophenol sodium salt hydrate is suitable for vitamin C determination. It acts as a redox dye to investigate the efficiency of gold nanoparticles (Au-NP) for the enzymatic activity of glucose oxidase. It is also used to compose UVB specific dosimeter and to measure the rate of photosynthesis. It serves as a good reducing agent.
